HP 50g Assume Integer
Hello,
Is there anyway to use the assume function or otherwise on the HP 50g to specify that a variable is an integer? i.e. like on the HP prime with assume(n,integer) Thanks

RE: HP 50g Assume Integer
I haven't found any. I do usually use a "Setup" or "Init" routine to initialize stuff for large programs. For integer stuff I clear flags 3 and 105. In the input stuff I'll use XQ.
I'm finishing off a set of programs to work with continued fractions and quadratic irrationals. I need something like "Assume Integer" too. I do use FLOOR rather than IP to keep things in integers. I've got programs to convert a fraction to a list of partial quotients and one to evaluate such a list into a succession of convergents. Now I have a new one (lots of fiddling around) that converts a quadratic irrational to the repeated its continued fraction and one to convert a list of partial quotients to the quadratic irrational (P+Sqrt(Q))/R.
